@JayDent I think that it’s possible, but it depends on what software you have available.
I just did a simulation using VCarvePro. I created a dome, arbitrarily sizing it to 3" in diameter. I didn’t spend any time figuring out the angle of the dome to make it match a baseball. That is possible, though. I carved out the dome just to get the shape. Obviously, you would not do that. You have the shape already = the baseball.
I created 3 lines of text on the dome. Then, I pocketed it out to a depth of 1/32" using a ball nose mill. In VCP, you have an option to project the toolpath onto the 3D model. I chose that. The carve looks good.
Now, if you have VCP, you can fake a tool using the diameter of your laser dot, and “carve” using that. If you have the laser module for VCP (I don’t.), that is all done for you.
If you don’t have VCP, this was all just a boring explanation. I suspect something could be done in Lightburn, but I have never used the Z axis option in LB so I can’t help at all on how to make it work. It could be fun to try, though. I see that you posted this question on the LB forum in May, but no one has replied, so I could be all wrong there.
Clearly, all of this is hypothetical. The optimal method would be a 4th rotating axis, as @ryanprice Ryan mentioned.
